By contrast, the Necessary and Proper Clause clearly grants incidental authorities upon Congress. This Necessary and Proper Article is sometimes called the elastic clause. This clause comes under the section VIII of the Article I, in the constitution of the United States. This clause empowered the Congress to enact the regulations required for the performance of its other authorities instituted by the Constitution. After the implementation of this clause, Congress possessed the power to ban racial segregation in the United States.
